A multi-level-architecture multi-fiber composite yarn includes a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial direction, and a matrix material included with the yarn, wherein the matrix material has a second anisotropic expansion coefficient that is different from the first anisotropic expansion coefficient in at least one of the axial or radial directions. A method of fabricating a multi-level-architecture multi-fiber composite yarn includes infiltrating a composite yarn having a first anisotropic expansion coefficient in an axial and/or radial directions with a matrix material having a second anisotropic expansion coefficient different from the first anisotropic expansion coefficient in the axial or radial direction.
